The two lovebirds met a year ago, but in the past few months their relationship blossomed.
As a devout Christian, Phyllis decided it was best to tie the knot.
"To tell you the truth, we fell in love with each other. I know you think that may be a little bit far-fetched for somebody our age, but we fell in love with each other."
The pair had previously lost two spouses and feel lucky to have found love again.
"Well, we were just compatible in a whole lot of ways, found ourselves enjoying each other's company," John added.
Congratulations to the newlyweds! John and Phyllis met while living at Kingston. At the young ages of 103 and 100 years...

The Cooks both live in the rest home and spend their time together enjoying meals, sitting in the sun and zipping down the halls in their mobility scooters.
Their age is certainly not a factor in their romance, with John being shy about the details.
However, they also like to give each other space.
"What we do, we keep both of our apartments. He's upstairs, and I'm down," Phyllis said.
The couple plans to keep busy and enjoy the rest of their time together.
